Titration for Acetic Acid in Vinegar Homework Help | Page 5

Questions
A. What is the average % acetic acid in your vinegar sample? Standard vinegar is 5% acetic
acid. How does your result compare with the standard?
B. Why is it better to use white vinegar rather than dark vinegar for this titration? C. Write a
balanced equation for the neutralization of acetic acid with NaOH.
D. How would your results have differed if the tip of the burette was not filled with sodium
hydroxide before the initial volume reading was recorded?
E. How would your results have differed if you had over-titrated, i.e. added NaOH beyond the
endpoint?
F. What happens if you don’t wear goggles and get some NaOH in your eyes?
G. A 5.0 mL sample of vinegar was titrated with 7.2 mL of 0.55 M NaOH(aq). If the density of the
vinegar solution is 1.00 g/mL, what is the mass percent of acetic acid present?
